Are you kidding us? I really don’t want to sound unkind, but I’m almost wondering if you’re winding us up? You eat PIZZA? Then SHREDDIES? And then you wonder why your blood sugar is sky high? And then it turns out that your “chicken and veg” meal actually included potato. And then to top it all, you tell us you drank a full-sugar Coke?
You are risking your health, your kidneys, your eyesight, your limbs - *please* reconsider your diet, this is so sad. It’s almost like you’ve read every single piece of advice here and decided to do the exact opposite.
In the end it’s your body. If you want to self-destruct because you want to eat pizza and drink Coke with 33g of sugar in it, and eat potatoes and, god help you, Shreddies, then there really isn’t anything anyone can do to stop you - you’re an adult, you make your own choices. But I can’t help thinking that if you’re coming on here and asking for advice, then at least on some subconscious level, you *must* care. Please try to harness that desire to make things better, or at least not any worse. You CAN stop eating these poisonous things - lots of people have. Even if you just cut down somewhat, to start with - you really couldn’t get a lot worse than what you’re doing now.
Your bad knee is irrelevant for now. Exercise is good, on the whole, but for someone with the disastrous diet and blood sugars that you have, to be honest your knee and lack of exercise is the least of your problems.
As to why it has *suddenly* got so bad - we can’t diagnose medical things here. But in T2D the pancreas can pack up, after years of abuse, and stop producing insulin altogether. No diet controlled T2 should be seeing blood sugars of 25, under ANY circumstances. I am very concerned for you medically.
Do take care {{{hugs}}}
